C7772A, F, G WALLPLATE TEMPERATURE SENSOR Table 2. Typical Resistance of Sensor Models. CHECKOUT Typical Resistance (in ohms) The C7772 Wallplate Temperature Sensor is immediately C7772A C7772F C7772G operational after wiring connections are made. Use an At 41°F (5°C) 54,200 25,392 23,467 accurate thermometer of ±1°F (0.5°C) to measure the temperature at the sensor location. To verify sensor accuracy, At 50°F (10°C) 41,758 19,901 18,789 use an ohmmeter to measure the resistance across the A
